Matrixx Initiatives, Inc. v. Siracusan. Nasal Spray
Decision Throws Corporations Off the Scent of
Materiality Definition
IN MATRIXX INITIATIVES, INC. V. SIRACUSANO,' THE UNITED STATES SUPREME
COURT considered whether a plaintiff bringing a securities fraud claim under the
Securities Exchange Act Section 10(b)' and Securities Exchange Commission
(SEC) Rule 10b-5' must allege that a pharmaceutical company's undisclosed
adverse event reports are statistically significant. Citing Basic Inc. v. Levinson,5 the
Court held that materiality turns on whether a reasonable investor would consider
the undisclosed information to have significantly altered the 'total mix' of available
information, stating that, while statistical significance is not required, something
more than allegations of adverse events alone is necessary.6 The Court's
something more standard makes it difficult for business entities to ascertain
materiality, and consequently, to know when a duty to disclose is triggered and for
courts to treat similarly situated defendants comparably. The Court's silence on
how to apply the standard across industries may initiate unnecessary disclosures of
non-material information, hindering an investor's informed decision-making.8
